Double click the green flag before starting the project.
Use the arrow keys to move around. :P
To everyone who's making a big deal about this and asking what's the point behind it: It's an engine, NOT A GAME. It's an engine that's meant to be freely used by anybody in their projects.
I know the engine has some problems, and that's because I made this years ago, so expect it to have some problems.
But feel free to use this, with or without credit!
:o Whaaaaaaaaaat? This got featured? A three year old project? I'm amazed by this.
